I solved it. Apparently Technic pack was ran with the integrated GPU instead of the Nvidia one. I just had to go ti Nvidia controll panel and set it to default. I post this so others can solve this error faster.

Launcher Version: 1.0.1.3 Operating System: Windows 8 Release preview build 8400 64bit Java Version: Version 7 Update 5 Antivirus Program: none ( built in Windows defender ) Description of Problem: After i choose a pack and download/start it , it opens the mods window with a frozen white screen and after about 5-10 seconds i get an error about bad video card drivers . I had this problem on Minecraft and solved it by reinstalling the drivers and it works perfectly but technic pack now has the same error and i don't know what to do . I reinstalled Java and the video drivers again and even deleted minecraft and technic pack folders and launchers but it still crashes on every mod pack. I have no idea what is going wrong and i don't think it is because i use Windows 8 because all programs work like a charm on it. I even tried compatibility mode and still I get the same error and runing the packs in developement build blocks with a white screen. I really want to play these packs so plz help me Error Messages: Error for Yogbox: http://pastebin.com/KmUA01eg Error Log: http://pastebin.com/cVKhWq97
